Texas Instruments CBL System Calculator-Based Laboratory with Case
The Texas Instruments Calculator-Based Laboratory System (CBL) is a portable and versatile data collection device for math and science. A wide variety of sensors, such as a Motion Detector, Dual-Range Force Sensor, pH system, Colorimeter, and Barometer, can be connected to the CBL interface. In this configuration the battery powered CBL could be uses a stand-alone data logger even outside the classroom for experiments.
An additional link cable connects the CBL to one of TI’s graphing calculators such as the a TI-73, TI-82, TI-83, TI-83 Plus, TI-83 Plus Silver Edition, TI-85, TI-86, TI-89, TI-92, TI-92 Plus and Voyage 200. Data is now collected under program control of the calculator and the systems is capable to analyze real-world data as a low-cost alternative to using computers.
The CBL system accepts three analog inputs, an ultrasonic motion detector input to connect the Calculator-Based Ranger CBR, a digital input channel with 4 discrete bits, and a digital output channel with 4 bits. The sampling rate is adjustable between 10,000 samples per second to one sample every 4 hours. Due to the own microcontroller and memory the CBL could be disconnected from the graphing calculator and act as a stand-alone device.
The software inside the CBL is powerful and includes:
Compute first and second derivatives on collected data.
Compute minimum, maximum, mean, and standard deviation statistics values on collected data.
Record absolute or relative time as data is collected.
Sophisticated data smoothing algorithms built in.
View data being collected on all active channels via the Channel View function (CH VIEW key).
6 different triggering options including sample on TRIGGER keypress.
